Greentelftth Fiber optic connectors are totally different than any other electronic or electrical connectors. They have to be perfectly clean in order to work. Most people are not aware of this fact and could easily overlook its importance. Another fact is that fiber optic connections are harder to trouble shoot in case of service outage. You may never need to clean the RJ45 connector for your computer's Ethernet network connection, then why do you need to clean a fiber optic connector if it serves the same purpose as a networking connection? While, the answer lies in how optics work differently than electronics. In electronics, as long as you have a contact between two connectors, they work perfectly; or at least most of the time. But for optics, light beams travel in straight lines, they bounce off whenever they hit anything and thus loss their energy. Fiber optic connectors are usually very sensitive thus prone to damage and contamination. To keep the devices in working condition for a long time, you should clean them regularly. There are many different ways to clean a fiber optic connector. They are not exclusive but rather complementary to each other. When one method failed, you can always try another method.
